Due to possible future expansion, I will be using Dantherm ducting, very smooth and lip-locked, the system will serve 2 machines for now, one is my Robland combination and the other will be the SCM sander.
The extractor is a Holytek 4kw 3200cfm 24 socks extractor ( similar to Dantherm s500) the main trunk will be 250mm, from the extractor inlet it will:
1. Go up 1m
2. 90 degrees bend(1.5x radius)
3. 2 m across the workshop.
4. Diverter valve
4a1. 90 deg bend down (1.5 x radius)
4a2. 250mm to 3x 150mm branch
4a3. Connect 3 x 150mm to the sander hoods
4b1. 240mm trunk carry on for another 2m (or add a reducer so trunk is 250mm to 150mm)
4b2. 90 deg bend (1.5 x radius)
4b3. Y branch from 250mm to 4 x 125mm ( or from 150m to 3 x 100mm)
4b4. Connect all the 125mm to the combo hoods
